Stacey Sager reports on the mental health history of the man who shot an NYPD officer in the Bronx

BEFORE THE SHOOTING

Bonds had returned home from his fast food restaurant job around 7:30 p.m. on July 4. Neighbors told police he was drinking with them at the corner.

At around 9 p.m., Bonds' girlfriend called 911, reporting he had wandered off. She said he seemed paranoid and was generally acting strangely.

She said she was concerned about Bonds and asked police to find him and check his welfare.

Asked by the operator if he was armed or violent, the girlfriend said no.

She gave them one street corner to look, and then another during a second call.

Police and an ambulance crew responded to the locations, but Bonds could not be found. The incident was classified as an "emotionally disturbed person" call and closed out.

THE INVESTIGATION

Police are investigating what may have prompted Wednesday's shooting, which Police Commissioner James O'Neill described as an officer being "assassinated in an unprovoked attack on cops."

"Officer Familia was murdered for her uniform and for the responsibility she embraced," O'Neill said in a message to officers Wednesday night. "For the NYPD, regularly achieving lower and lower crime figures means absolutely nothing when one of our own is brutally shot and killed."

Familia worked her entire police career in the Bronx precinct where she was killed while staffing the RV-like command post, stationed to help combat rising crime in the neighborhood after a triple shooting in March.
